new ipython / old django
IPython after version 0.10 is not friends with older Django (e.g.
1.1.x) versions anymore.
shell = IPython.Shell.IPShell(argv=[])
AttributeError: 'module' object has no attribute 'Shell'
This is fixed in newer Django’s, but this isn’t backported.
Here, a patch. (Nothing more than a diff between the old and the new Django version.)

And another patch to get the classic

TerminalInteractiveShell() would require a
config=load_default_config() from IPython.frontend.terminal.ipapp.)
